Guys, I have a 2015 2500 with 70K, and the turbo actuator went bad.

I was thinking of just going with the city diesel upgrade or a Fleece Cheetah or turbo time Dominator turbo.

The truck has a full tune, FASS 165 fuel, Fleece CP3, and ARP 625 studs.

Trans was rebuilt using Revmax parts, and they said it is good to around 550 HP.

So my question is, what would I gain from the upgraded turbo?

Would I gain any noticeable improvement in power?

No towing, just a daily driver-Is it worth the extra $$ to go with a new turbo?

Thanks so much for the advice
